CodeQuest is an international eTwinning project that transforms language learning into an exciting game-based adventure. Students complete eight creative levels while improving their English, digital literacy, creativity, collaboration, and problem-solving skills. Throughout the project, they design AI prompts, create Canva Code games, build interactive activities in Genially, produce 3D pen models, prepare sand art vocabulary pages, complete QR missions, and showcase their work in a final international exhibition. Using safe and responsible AI tools, students become creators rather than consumers of technology. Every level ends with a tangible product, encouraging active participation, teamwork, and real-world learning. By combining gamification, STEAM, digital storytelling, and project-based learning, CodeQuest creates an engaging environment where students learn, create, code, and explore together while developing essential 21st-century skills.
